The effective thriller, “The Ones Below”, deals with two neighbor couples expecting their first child and the terrible happenings that follow the loss of a baby.

The Londoners Kate (Clémence Poésy) and Justin (Stephen Campbell Moore), after giving it a good thought, are going to have a child and are feeling great about it. When not working, they carefully plan every detail while moving into the upper flat of a townhouse that was divided horizontally into two.The ones who live below are the English-Finnish Theresa (Laura Birn), and her successful husband, Jon Baker (David Morrissey). They’re living a dream since she's finally pregnant after seven years attempting to conceive.Kate develops a strange curiosity for Theresa, who seems very sympathetic, carefree, and enjoying a stupendous phase in her marriage and life.

The women eventually become closer, but the first meeting of the couples comes draped in tragedy. Kate invites the Bakers to dinner, but the couple doesn’t seem so happy as before. Theresa shows to be unstable and drinks a few glasses of wine, despite forbidden by Jon, who in turn, adopts a judgmental posture that visibly bothers the hosts. He acts violently after Theresa falls down the steep stairs. This anguishing incident makes Theresa lose the fetus.

From this point on, the couples cut relations and the Bakers depart to Germany. They return a few months later, willing to forget what happened and ready to make amends with their neighbors. Theresa even shows availability to take care of Kate's newborn, Billy. However, abnormal behaviors and frightening occurrences put Kate and Justin alert, as the story grows creepy in its conclusions, embracing an impenetrable darkness.

Even without blowing your mind with his statement, David Farr, who co-wrote the screenplay of “Hanna” five years ago, had a favorable directorial debut. This slow-burning thriller was able to cause a good impression and got my attention from start to finish, also thanks to the consummate performances of the well-selected cast.
